MYSQLI_STMT_FETCH(3)							 1						      MYSQLI_STMT_FETCH(3)

mysqli_stmt::fetch - Fetch results from a prepared statement into the bound variables

       Object oriented style

SYNOPSIS

       bool mysqli_stmt::fetch (void  )

DESCRIPTION

       Procedural style
       bool mysqli_stmt_fetch (mysqli_stmt  $stmt)

	Fetch the result from a prepared statement into the variables bound by mysqli_stmt_bind_result(3).

       Note

	       Note that all columns must be bound by the application before calling mysqli_stmt_fetch(3).

       Note

	       Data  are  transferred  unbuffered  without  calling mysqli_stmt_store_result(3) which can decrease performance (but reduces memory
	      cost).

PARAMETERS

	      o $
		stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3).

MYSQLI_STMT_STORE_RESULT(3)						 1					       MYSQLI_STMT_STORE_RESULT(3)

mysqli_stmt::store_result - Transfers a result set from a prepared statement

       Object oriented style

SYNOPSIS

       bool mysqli_stmt::store_result (void  )

DESCRIPTION

       Procedural style
       bool mysqli_stmt_store_result (mysqli_stmt  $stmt)

	You  must  call mysqli_stmt_store_result(3) for every query that successfully produces a result set ( SELECT, SHOW, DESCRIBE, EXPLAIN), if
       and only if you want to buffer the complete result set by the client, so that the subsequent  mysqli_stmt_fetch(3)  call  returns  buffered
       data.

       Note

	       It  is unnecessary to call mysqli_stmt_store_result(3) for other queries, but if you do, it will not harm or cause any notable per-
	      formance in all cases. You can detect whether the query produced a result set by checking if mysqli_stmt_result_metadata(3)  returns
	      NULL.

PARAMETERS

	      o $
		stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3).

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      /* Open a connection */
	      $mysqli = new mysqli("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20";
	      if ($stmt = $mysqli->prepare($query)) {

		  /* execute query */
		  $stmt->execute();

		  /* store result */
		  $stmt->store_result();

		  printf("Number of rows: %d.
", $stmt->num_rows);

		  /* free result */
		  $stmt->free_result();

		  /* close statement */
		  $stmt->close();
	      }

	      /* close connection */
	      $mysqli->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      /* Open a connection */
	      $link = mysqli_connect("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20";
	      if ($stmt = mysqli_prepare($link, $query)) {

		  /* execute query */
		  mysqli_stmt_execute($stmt);

		  /* store result */
		  mysqli_stmt_store_result($stmt);

		  printf("Number of rows: %d.
", mysqli_stmt_num_rows($stmt));

		  /* free result */
		  mysqli_stmt_free_result($stmt);

		  /* close statement */
		  mysqli_stmt_close($stmt);
	      }

	      /* close connection */
	      mysqli_close($link);
	      ?>

	      The above examples will output:

	      Number of rows: 20.
